I don't think that this Flt Lt is a particularly good example of a Service doctor to serve up as a reason to join or leave. He is obviously not suited for Service life, but I'm not sure that prison was the best answer. A nice, quiet, "Thanks for trying" and discharge would have been a far better approach.
He isn't among the ranks who bleat about poor pay, though, he hadn't reached that level of qualification or practice. If the Times article is to be taken seriously in reference to poor pay, it hasn't checked on how many doctors leave because of it. Lots bleat and sabre-rattle, but most see out their commissions regardless!
UK doctors should look to most of our European partners and what their doctors are paid in relation to themselves and thank the Lord that the British public hasn't wised up to their excessive demands before this!
